salt.cloud.clouds.ec2

The EC2 Cloud Module

The EC2 cloud module is used to interact with the Amazon Elastic Compute Cloud.

To use the EC2 cloud module, set up the cloud configuration at
/etc/salt/cloud.providers or /etc/salt/cloud.providers.d/ec2.conf:
my-ec2-config:
  # EC2 API credentials: Access Key ID and Secret Access Key.
  # Alternatively, to use IAM Instance Role credentials available via
  # EC2 metadata set both id and key to 'use-instance-role-credentials'
  id: GKTADJGHEIQSXMKKRBJ08H
  key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
  # The ssh keyname to use
  keyname: default
  # The amazon security group
  securitygroup: ssh_open
  # The location of the private key which corresponds to the keyname
  private_key: /root/default.pem

  # Be default, service_url is set to amazonaws.com. If you are using this
  # driver for something other than Amazon EC2, change it here:
  service_url: amazonaws.com

  # The endpoint that is ultimately used is usually formed using the region
  # and the service_url. If you would like to override that entirely, you
  # can explicitly define the endpoint:
  endpoint: myendpoint.example.com:1138/services/Cloud

  # SSH Gateways can be used with this provider. Gateways can be used
  # when a salt-master is not on the same private network as the instance
  # that is being deployed.

  # Defaults to None
  # Required
  ssh_gateway: gateway.example.com

  # Defaults to port 22
  # Optional
  ssh_gateway_port: 22

  # Defaults to root
  # Optional
  ssh_gateway_username: root

  # One authentication method is required. If both
  # are specified, Private key wins.

  # Private key defaults to None
  ssh_gateway_private_key: /path/to/key.pem

  # Password defaults to None
  ssh_gateway_password: ExamplePasswordHere

  driver: ec2

  # Pass userdata to the instance to be created
  userdata_file: /etc/salt/my-userdata-file

salt.cloud.clouds.ec2.optimize_providers(providers)

Return an optimized list of providers.

We want to reduce the duplication of querying the same region.
